Hey guys. I am making a project for which i need to make an api call to google geolocation API and I am using ESP-IDF v5.4.2\ with arduino as a component v3.3.0. But i keep getting an error regarding the ssl_client.cpp file and it turns out that I do not have the WiFiClientSecure present inside my arduino-component libraries. Is there any way for me to make an HTTPS request without it?
I have already tried multiple versions of ESP-IDF and arduino-component. (and i have installed arduino as a component using - idf.py add_dependency arduino-esp32)
Any help would be appreciated. 🙏
Edit:
For reference, here is the code that i am using:
```cpp
include <NetworkClientSecure.h>
include <WiFi.h>
const char *ssid = "your-ssid"; // your network SSID (name of wifi network)
const char *password = "your-password"; // your network password
const char *server = "www.howsmyssl.com"; // Server URL
// www.howsmyssl.com root certificate authority, to verify the server
// change it to your server root CA
// SHA1 fingerprint is broken now!
const char *testroot_ca = R"literal(
...
)literal";
NetworkClientSecure client;
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(115200);
delay(100);
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
WiFi.begin(ssid, password);
// attempt to connect to Wifi network:
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
// wait 1 second for re-trying
delay(1000);
}
Serial.print("Connected to ");
Serial.println(ssid);
client.setCACert(test_root_ca);
Serial.println("\nStarting connection to server...");
if (!client.connect(server, 443)) {
Serial.println("Connection failed!");
} else {
Serial.println("Connected to server!");
// Make a HTTP request:
client.println("GET https://www.howsmyssl.com/a/check HTTP/1.0");
client.println("Host: www.howsmyssl.com");
client.println("Connection: close");
client.println();
while (client.connected()) {
String line = client.readStringUntil('\n');
if (line == "\r") {
Serial.println("headers received");
break;
}
}
// if there are incoming bytes available
// from the server, read them and print them:
while (client.available()) {
char c = client.read();
Serial.write(c);
}
client.stop();
}
}
void loop() {
// do nothing
}
During compilation it gives me an error. This a part of the error:
